77e271cb4e prefer to generate constant pool loads over splats. This prevents us from 
using a splat for {1.0,1.0,1.0,1.0}

1d2e995fc1 Lower BUILD_VECTOR to VECTOR_SHUFFLE if there are two distinct nodes (and if 
the target can handle it). Issue two SCALAR_TO_VECTOR ops followed by a
VECTOR_SHUFFLE to select from the two vectors.

994d8e6bd4 For targets with FABS/FNEG support, lower copysign to an integer load,
